Installing the DC21X4 Driver on Windows NT: 1. From the Windows NT Main Menu, select the Control Panel icon. 2. From the Control Panel menu select the Network icon. If a dialog box asks you "Do you want to install NT Network?" select YES and Continue. Then place the Windows NT CDROM in the CD-ROM reader. Select the drive that matches the configuration of your system and complete the install. 3. You will see several messages. To add a network adapter, select Yes and then Continue 4. For each additional message, select continue. 5. From the Add Network Adapter dialog box, scroll through the menu to select Other. 6. When the Insert Diskettes menu prompts you for a disk, insert the DC21X4 driver installation diskette for Windows NT into drive A. Then select OK. 7. Select your option [Digital Semiconductor 21040 based Ethernet Controller] [Digital Semiconductor 21041 based Ethernet Controller] [Digital Semiconductor 21140 based 10/100 mbps Ethernet Controller] [Digital Semiconductor 21142 based 10/100 mbps Ethernet Controller] [Digital Semiconductor 21143 based 10/100 mbps Ethernet Controller] [Digital Semiconductor EB40 21040 based Evaluation Board] [Digital Semiconductor EB41 21041 based Evaluation Board] [Digital Semiconductor EB140 21140 based Evaluation Board] [Digital Semiconductor EB142 21142 based Evaluation Board] [Digital Semiconductor EB143 21143 based Evaluation Board] from the Select OEM Option box, then select OK. 8. Modify the default distribution path in the Windows NT Setup box to point to the correct drive and path, then click on [Continue] 9. For PCI options, a Dialog box pops up to select the: ConnectionType: ------------------------------------------------------------------- Digital Semiconductor's DC21040 ------------------------------------------------------------------- o AutoDetect In AutoDetect mode the driver checks first the Twisted Pair port.

Upon completion, the selected adapter is added to the Installed Adapter Cards list of the Network Setting box (the number prefixing the adapter is the adapter number). 11. Click on [Close] to complete the Network Setting initialization. 12. If needed, modify the values in the registry (see section 7 below). 13. Shutdown and reboot the system. B. Parameters To overwrite the initial values set by the EISA Configuration Utility (ECU) overwrite the driver's default values, add or edit the following values in the Registry DC21x4_<adapter_number> Parameters subtree: CacheLineSize = REG_DWORD { 16 | 32 | 64 | 128 } 16 bytes 32 bytes (default) 64 bytes 128 bytes MapRegisters = REG_DWORD {4,8,16} (default: 16(alpha) | 8) Number of map registers allocated by the adapter. MemoryReadMultiple = REG_DWORD { 0 | 1 } (21142,21143 only) 0 Disabled (default) 1 Enabled Enable/disable PCI Memory_Read_Multiple command. MRM should be enabled when the DC21X4 is connected to the TI1130 PCI/CardBus bridge. ReceiveBuffers = REG_DWORD {8..64} (default: 16) Number of buffers allocated by the driver in the Receive ring. SoftwareCRC = REG_DWORD { 0 | 1 } (DC21040 rev 1.x, 2.0 & 2.2 only) 0 The CRC is generated by the adapter 1 (default) The CRC is generated by software for transmit packets bigger than the transmit threshold. NOTE: This option affects performances and could be disabled if the adapter does not report transmit underruns in its statistic counters UnderrunThreshold = REG_DWORD number_of_underruns (default=10) (21140 and 21143/2 only) Maximun number of underrun occurences before the controller switches to the next threshold value. The following values allow to overwrite the DC21X4 default setting.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
